Function

Description

Interface Schematic

1VREF/PD

For low noise amplifier applications, this pin is used to control the bias

current. An external resistor can be used to set the bias current for any

VPD voltage.

2GND1

Ground connection. For best performance, keep traces physically short

and connect immediately to ground plane.

3RF IN

RF input pin.

4RF OUT

Amplifier output pin. This pin is an open-collector output. It must be

biased to VCC through a choke or matching inductor. This pin is typi-

cally matched to 50

Ω with a shunt bias/matching inductor and series

blocking/matching capacitor. Refer to application schematics.

5GND2

LNA emittance inductance. Total inductance is comprised of

package+bondwire+stripline (L1) on PCB.

SELECT

This pin selects high gain and bypass.

Select < 0.8V, high gain.

Select > 1.8V, low gain.
